Abstract
Various novel concepts and schemes pertaining to non-orthogonal multiple access for wireless communications are described. A group orthogonal coded access (GOCA) scheme is introduced to reduce multi-user interference (MUI) and improve performance. A repetition division multiple access (RDMA) scheme is introduced to differentiate user equipment (UEs) by different repetition patterns. A low-density spreading (LDS) scheme is introduced to reduce MUI and improve performance.
